gcc can't find libio.h

[Kurt Sheffer]

Hi,
	I recently installed the "server" install of YDL 2.1 on my 7200/75. 
This did not include gcc. I installed all of the rpms from the CD that 
contained "gcc", "g++", or "c++". I happily tried to install npasswd, 
and Configure told me that gcc was broken.  Trying to compile a 
four-line c++ program with one cout as a test, I received this:

In file included from /usr/lib/gcc-lib/ppc-yellowdog-
linux/2.95.4/../../../../include/g++-3/iostream.h:31,
                  from /usr/lib/gcc-lib/ppc-yellowdog-
linux/2.95.4/../../../../include/g++-3/iostream:6,
                  from main.cpp:1:
/usr/lib/gcc-lib/ppc-yellowdog-
linux/2.95.4/../../../../include/g++-3/streambuf.h:36: libio.h: No such 
file or directory

Obviously I missed some libraries somewhere... can anyone point them 
out? Any suggestions would be much appreciated.

Thanks,
Kurt
